HEAT-DEELECTING DEVICE FOR; AIR REGISTERS, ETC.

Application filed Septemberm, 1925. Serial No. 56,083.

This invention relates to warm air deflectors that may be advantageously used in connection with registers, radiators, electric heaters and various kinds of heating or cooking apparatus from which heated air may be deflected in a desired direction for warming a compartment in which the heating apparatits is located or connected thereto, for in stance a compartment having" a wall or floor register con'nnunicating with the outlet flue of a hot air furnace. i

The primary object of my invention is to provide a, warm air drflector that may be mounted a wall having a. register, so as to receive the warm air prior to entering the compartment. lhe device includes two chambers, one of which receives the was-m air and collects dust or other Foreign matter carried .rehy while the other chamber directs the warm air towards the floor of the coin 'iartinent so that he floor will be heated. it is a well known fact that warm air ascends to the ceiling; of a con'ipartment with the result that the hoor is ordinarily cold, but with my device the warm air will be deflected against the floor and in rising to wards the ceiling heat the compartment.

Another object'ot this invention is to provide warm air deflector that may be mounted over floor register or the heating device supported on the floor. for instance a radia tor or electric heater. In either instance, the warm air is deflected towards the floor, and

this same device with slight modification.

may be mounted on a stove or other heater.

A. still further object of this invention is to provide a simple, durable and inexpensive sheet metal deflector that may be finished to harmonize with the wall or floor of the room and the construction of the deflector Will be hereinafter specifically described and then claimed.

Reference will now be had to the drawing, wherein v Figure l is a vertical sectional view of the deflector in connection with the Wall register;

Fig. 2 is a view illustrating a slight modication of the wall deflector;

Fig. is a similar view of a deflector connection with an electric heater;

Fig. i is a similar view of a deflector connection with a floor register;

Fig. 5 is similar view of a deflector in connection With a radiator. illustrating a slight modification of my invention, and

*ig. 6 a vertical sectional view of another torm ot deflector in connection with a floor register.

Reference will first be had to Figs. land 2 showing a ,floor 1 and a wall 2, said Wall having warm air outlet member or register 3. which is ordinarily above the Waist board of the Wall. Considering Fig. 1 there is a dust collecting casingo resting on the floor 1 and a rear wall of said casing has opening- 6 in alinement with the register 2-3. said opening being covered by a conventional form oi screen 7 which is adapted to collect dust and other foreign matter from the warm air. This screen may be somewhat coarse compared to another screen 8 over the upper open end of the casing 5 and both of said screens may be detachable so as to be easily cleaned from time to time. The screens cooperate with the casings 5 in forming; a dust chamber 9 in the bottom of which may settle dustand other foreign matter.

Ii tounted over the casing 5 is a deflector casing 10 having a lower bell shaped outlet opening 11 in spaced relation to the floor 1 andthe casing 5. The top and side walls of the deflector casing 10 may be suitably connected to the wall 2, as at 12. and mounted in the deflector casing 10 an angularly dis posed deflecting Wall 13 which may be secured to the top of the casing 10 and to the wall 2, so that warm air passing through the screen 8 will be deflected. outwardly into the casing 10 and then downwardly through the passage or chamber 14 oi said casing to escape in proximity to the floor 1. The inner dust collecting casing 5 cooperates With the outer deflector casing 10 in providing a tortuous or sinuous passage for the warm air and in allowing the air to escape at the floor 1 the compartment above the floor will be more thoroughly and quickly heated; the cold air being driven from the floor 1 upwardly or at least commingling With the warm air so that there is an even temperature in the compartment to be heated by warm air from the register 3.

Considering Fit 2 a dust collectinginner casing 15 is shaped to provide clearance for the Waist board 4 and this inner casing has a single screen 15. An outer deflector casing 17 rests on the floor l. and has an outlet opening 18. The deflector wall 13 is dispensed with and the configuration of the inner and outer casings 15 and 17 is such that the warm air is carried cownwardly between said casings and escapes at the floor 1.

Reference will now be had to Figs. 4 and 6 wherein a floor 18 has a register or outlet member 19. As shown in Fig. 4, there is an inner casing 20 having a wall 21 in common with an outer dome shaped casing 22 having an outlet opening 23 in proximity to the floor 18. The top of the inner casing 20 has a screen 24, and this form of my device causes the upwardly ascending warm. air to be returned to the floor 18. The same result is attained by the device shown in Fig. 6, consisting of an inner casing 25, an outer dome or bell shaped casing 26, a screen 27, and diverging deflector walls 28 which are adapted to support the casing 26 relative to the casing 25. Thus far my devices are for warm air outlet members or registers, but as set forth in the beginning a device may be used in connection with a heating apparatus. As an instance of such apparatus there is shown an electric heater 29 in Fig. 3, said heater being set in an inner casing 30 having a wall in common with an outer dome shaped casing 31, somewhat similar to the casing 22. The inner casing 30 may have a bottom wall 32 supporting the heater 29 and the common wall of t .e casings 30 and 31 has an air inlet 'ipening 33. Air entering the opening 33 impinges against the heater 29 and is heated within the casing 30 to pass upwardly and then downwardly between the casings 30 and 31. into a compartment.

Some compartments may be heated by a steam or hot water radiator 34 and my device may be made to set downwardly over the radiator and inclose the same. There is an inner casing 35 having a wall in common with an outer casing 36 and cold air may be idmitted to the inner casing through bottom end openings 37 so that the air will circulate about the radiator and then be deflected downwardly between the casings 35 and 36 to escape in proximity to the floor of the compartn'ient.

In all forms of my invention there are inner and outer casings with the inner casings affording a dust collecting chamber and the outer casmg a passage or chamber which will cause warm air to be deflected downwardly in proximity to a floor. These casings are made of light and durable sheet metal that may be finished so that the device will present a neat appearance and in the majority of instances the device is set on a floor or against a wall without being secured thereto, so that the wall or floor is not marred by any fastening means when the device is removed in the summer time. It is obvious that the device as shown in Figs.

1 and 2 may be attached to the front of an open oven or the device shown in Figs. 4 and 6 placed over a gas burner. In either instance there is a source of heat for heating air that may be deflected downwardly instead of immediately ascending.

The preferred embodiments of my invention have been illustrated, but it is to be understood that the structural elements are susceptible to such variations and modifications as fall within the scope of the appended claim.

What I claim is A heat deflector for air heating devices, con'iprising a casing adapted to be mounted against a vertical wall having an air outlet opening, said casing having a closed top, and a vertical partition extending in proximit to the closed top of said casing and dividing said casing into communicating chambers with one of said chambers adapted to receive warm air and collect dust from the wall opening, and the other chamber having a bottom opening adapted to direct air in a lateral direction, and a screen supported from the upper edge of said partition and through which screen passes air from one chamber to the other.

In testimony whereof I allix my signature.

SAMUEL I. NICKLE.
